Thanks Avi - yes, there is a bit of melancholy. At weddings, I always feel bad for the father when he does the dance with his daughter. To me, it's like it's the last time it will truly be father and daughter...everything after that is different - hence the title. Sort of bitter-sweet I guess you could say.
Actually, he was probably just thinking, " Holy $hit - how much is this wedding going to cost me..." - which is melancholy in and of itself. LOL
